From 786a2aa281f4c4ba424ea8b8ea1e85ab62c4a57c Mon Sep 17 00:00:00 2001 From: Jarkko Sakkinen Date: Mon, 6 Jul 2020 23:53:42 +0300 Subject: [PATCH] Revert commit e918e570415c ("tpm_tis: Remove the HID IFX0102") Removing IFX0102 from tpm_tis was not a right move because both tpm_tis and tpm_infineon use the same device ID. Revert the commit and add a remark about a bug caused by commit 93e1b7d42e1e ("[PATCH] tpm: add HID module parameter").
